Unlocking the Impermeable Reservoir: Lessons from a 30-Year Reservoir Engineer An Alphaxioms interview with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Context: Menengai East and Olkaria Central. Every geothermal developer knows the moment. The rig is gone and the money is spent. The well is drilled to depth, the temperature is there, and then the well will not flow. The heat is real, but the connection between the well and the reservoir is not. Wells like this sit at the centre of one of the most important questions in geothermal development: what do you do with a tight reservoir? Walk away and drill again, or find a way to unlock what is already there? To explore the question, Alphaxioms spoke with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Richard brings 30 years of global experience in geothermal energy. We framed our questions around two settings, Menengai East and Olkaria Central, and asked him how ...
Hungary Unlocks 29 Billion Forint for Geothermal Drilling: Jedlik Ányos Program Fuels Major Expansion in Europe's Geothermal Hotspot
Hungary's Geothermal Boom: Jedlik Ányos Energy Program Unlocks 29 Billion Forint for Deep Earth Exploration and Green Heat
Posted by: Alphaxioms Geothermal News
Date: March 6, 2026
Hungary is stepping up its game in the geothermal arena with a major push under the
Jedlik Ányos Energetikai Program (Jedlik Ányos Energy Program). As of early March 2026, fresh funding calls have opened, making a combined 29 billion footprint (approximately USD 80-85 million) available specifically for geothermal projects. This includes non-repayable grants to de-risk exploratory drilling and interest-free loans for larger-scale developments. For a country already in Europe's top tier for geothermal utilization thanks to the favorable geology of the Carpathian Basin, this is a game-changing injection that could accelerate the shift toward energy independence, lower heating costs, and reduced fossil fuel imports.
Hungary's Exceptional Geothermal Advantages
Hungary sits on some of the best geothermal conditions in Europe. The crust here is only about half as thick as the European average, leading to higher subsurface temperatures closer to the surface. Sedimentary rocks in the Pannonian Basin store vast amounts of natural hot water, making shallow and deep geothermal resources accessible with relatively lower drilling risks compared to many other regions.
Geothermal energy is a true baseload renewable: it's available 24/7, independent of weather or daylight, and emits far fewer greenhouse gases than fossil fuels. In Hungary, it's already widely used for district heating, spa tourism, agriculture (greenhouses), and industrial processes. Current installed capacity focuses mostly on direct heat use, with production around 6.4 petajoules annually. The **National Geothermal Utilization Concept** aims to double this by 2030—pushing geothermal's share in total heat production from around 6.5% to 25-30%. If achieved, new applications could displace 1-1.2 billion cubic meters of natural gas by 2035, significantly cutting import dependency and enhancing energy security.
However, geothermal projects carry high upfront costs and geological risks—especially for exploratory wells where success isn't guaranteed. That's where state support becomes crucial to attract private investment and scale up the sector.
Breaking Down the New 29 Billion Forint Geothermal Funding
The Jedlik Ányos Program—named after the 19th-century Hungarian inventor Ányos Jedlik—delivers record-breaking resources for energy transitions. Three dedicated geothermal calls form the core of this push:
1.Interest-Free Loan Program (19 Billion Forint)
Launched on March 2, 2026, this is the largest slice. Businesses can access interest-free loans for geothermal heat production investments outside Budapest.
- Deep geothermal projects: Minimum 1 billion forint, maximum 6 billion forint per project.
- Shallow geothermal: Minimum 100 million forint, maximum 1 billion forint (with only 10% of the total budget allocated here).
Nearly two-thirds of funds prioritize less-developed regions. Repayments can extend to November 2029.
This facility lowers financing costs dramatically, enabling larger, more ambitious developments like enhanced district heating networks or industrial applications.
2.Drilling Risk Mitigation Grant (10 Billion Forint)
Also opened March 2, 2026, this non-repayable support targets the high-risk first exploratory wells in 10-20 rural projects. Grants range from 40 million to 1 billion forint per project.
- If drilling succeeds (hot water/steam found in viable quantities), the state covers up to 10% of eligible costs.
- If it fails, coverage can reach 50%—a strong de-risking mechanism to encourage more exploration.
Applications are accepted in phases (first window until end of April 2026, second in autumn), with physical completion required within two years of contract signing, no later than end-2028.
3. Geothermal Power Generation Support (12 Billion Forint)
This call opened earlier in January 2026 and supports grid-connected systems combining heat and electricity production from existing wells. The full amount can fund a single large project, making it ideal for pilot binary cycle or ORC (Organic Rankine Cycle) plants that generate power alongside heat.
Together, these three calls total 41 billion forint targeted at geothermal, part of the broader Jedlik Program's nearly 130 billion forint for various energy developments in 2026. Other related initiatives include 50 billion forint for industrial energy storage and 38.7 billion forint in loans for energy efficiency upgrades at rural sites.
Real-World Impact and Examples
These funds arrive at a pivotal time. Successful geothermal projects could transform district heating in cities and towns—replacing gas boilers with sustainable hot water from the ground. For instance, Budapest Airport has explored geothermal integration with monitoring systems to ensure safe, long-term aquifer management; if scaled, it could slash direct CO2 emissions by over 90% by 2030.
In agriculture and industry, geothermal greenhouses and process heat reduce energy bills and emissions. The de-risking grant is particularly exciting for smaller players or new entrants, as it encourages drilling in untapped areas.
If fully utilized, this package positions geothermal as a flagship sector in Hungary's green economy. It supports national goals of self-sufficiency, affordable energy, and decarbonization while creating jobs in drilling, engineering, and operations.
Why This Matters Globally and for the Geothermal Community
Hungary's approach offers a model for other countries with sedimentary basin resources but limited exploration due to risks. By combining loans for proven projects and grants for risky first steps, it balances ambition with pragmatism. In a world facing energy price volatility and climate targets, expanding stable renewables like geothermal is essential.
For geothermal enthusiasts and investors, 2026 looks promising in Hungary. Applications are live—check official portals like palyazat.gov.hu for details and deadlines. Whether you're a developer eyeing deep wells or a municipality planning district upgrades, these incentives lower barriers significantly.
As always at Alphaxioms, we're tracking how this unfolds. Will we see a surge in new wells and power plants? Share your thoughts below—what Hungarian geothermal project excites you most?
